DREDGE FOR POWDER-CANS.

Specification of Letters Patent.

Patented June 21, 1910.

Application filed May 20, 1909. Serial No. 497.277.

T 0 all whom it may concern:

Be it known that 'I, Enn. ll. W. Uuancn, a citizen of the United States,and resident of Chicago. in the county of Cook and State of Illinois.have invented certain new and useful Improvements in Dredges for.lowder-Cans; and I do hereby declare that the following description ofmy said invention. taken in connection with the accompanying sheet ofdrawings forms a full clear, and exactv specification. which will enableothers skilled in the art to which it appertains to make and use thesame.

This invention has general reference to metallic. cans for powders ofall kinds such as spices, talcum and other powders; and its object is toprovide such cans with a convenicnt. serviceable and el'ticient dredgefor sifting the contents of said cans tron the same.

In the drawings already referred to, which serve to illustrate thisinvention more fully, .l igure l is aperspective view of a can providedwith my improved dredge. Fig. 2 is an elevation of a similar can. partlyin section to show the construction of the dredgeportion of the. can.Fig. 3 is a plan of a dredge-device o't' oblong contour. Fig. 4: is asectional view of the same on line 2v .2; of Fig. 3.

Like parts are designated by corresponding characters and symbols in allthe figures.

The reference letter A in the drawings designates a 'an of any desiredsize. shape or construction and consisting of the usual body It providedwith a bottom 15 and a top or cover I). the bottom and top beingattached to the body in any of the manners now in vogue, such as asoldered slip-joint, crimped. imitation. or genuine double seam, whilethe top .l, may also be a slip, or removable, cover. my invention beingapplica ble to every can now being produced. In the 'top B of this canthere is a central, raised. portion 17. in which there is an opening 18for'filling the can and dumping its contents when desired. andtransversely across the top of this raised portion 17 there is adepression or groove 19, as clearly illustrated in Figs. 2 and 4. Overthe raised portion 17 in the top B there is removably placed a cover Cwhich cover fits the raised portion 17 a. snug fit and it has in itstop, and omone side thereof, a series of perforations 20. whichperforations are so spaced that when the cover C is placed so that theseI perforations are over the filling opening 18, as shown in Fig. 2.there is a free passage from the interior of the can A through saidperforations. in this cover C there is also a depression 21. registeringwith the depression 19 in the top B. This cover C has i laterallyprojecting flange 22. as the lower end of its rim 23, the rim being of.less depth than the raised portion 17 so as to atlord a narrow space 2tbetween said flange 2-2 and the top B which enables a knife or othersuitable instrument being placed into this space to pry the cover offthe projecting portion 17 should the same be held thereto rather tightlyas it might happen when the parts are made in dies in large quantitiesand their sizes vary slightly owing to wear in said dies. The raisedportion 17 in the top B may be of oblong contour, as shown in thefigures. or any other analogous shape, but in order that the cover C maybe reversible. the shape must be symmetrical on both sides of thetransverse groove. or depression 21.

it is evident that. instead of metallic can, the latter may beconstructed with a paper bod and bottom. or the canbody may be drawnseamless with an integral bottom. itbeing preferred only, that the topwith its upwardly projecting portion and the cover C for the latterportion be made from sheet-metal.

it will be observed that the depth of the projecting portion of the topof the can exceeds the depth of the cover C. lhis construction insuresthat the two surfaces having the perforations will always be in closecontact and that when the cover is so placed that the perforations donot register, there can be no leakage of powder from the can. Thelaterally projecting flange on the rim of the cover serves the purposeof providing means whereby the cover may be pried ofi' the can, and atthe same time functions as a reinforce to the rim to prevent the latterfrom stretching when the cover has been repeatedly removed from the can.

I have heretofore stated that the project ing part of the can has thefilling anddischarge opening as described, that; is to say, located onone side of the transverse center line of said projecting portion. andthat the cover has the perforations therein also located on one side ofits transverse center line. This construction n1a7y ,-however, bereversed in cans l:a.i.og a. s ip-on cover y an ent-i rely adapted foruse to and in the claims I c-ain1 a can for powdered it Will uncoversaid substances; but I desire it to be distinctly understood that thesecans are also adapted for use in connection with ground, granulated orcomminuted substances. I also desire it understood that in mentioningcans I wish to include cartons and all other packages adapted to receivea cover fitted with my'improved dredge.

In addition to its serving as a means to locate the cover C correctlyupon the projecting portion 17 of the top, the depressions l9-and 21serve as a shut-oil or cut-off to prevent the eomminuted substances fromes--- caping or leaking from the can when the dredge openings are closedby the cover or vice-versa.

Having this fully described this invention, I claim as new and desire tosecure to me by Letters Patent of the United States 1. A can adapted tohold powdered and pulverized substances, comprising a canbody; a top forsaid can-body; a pro jecti'on on said top, there being in the topof saidprojection a filling and dumping opening located on one side of thecenter line of said projection; a cover for said projecting portionremovably located thereon; a central depression in the top of saidprojecting portion and a corresponding 1 pro ection on said coveradapted to engage said depression; there being one or more openings insaid cover, said openings being so located that when the cover is placedupon the projecting portion in one position dumping opening, and whenremoved and reversed upon said projecting portion, it will close saiddumping opening.

2. A can closed on. top with the exception "of an opening at one side ofa center line and a cover for engagin the can top, said cover beingclosed with t 1e exception of one or more openings at one side of acenter line, said cover being adapted for different applications to saidbox but only by'bodily rethe cover on the top causing all openings toinoval of the cover during change from one position to another, oneposition of said cover on said top causing the cover and box openings toregister and another position of beclosed.

3; A can closed on top with the exception of an opening at one side of acenter line and a cover for engaging the can top, said cover beingclosed with the exception of one or more openings at one side of acenter line, said cover being adapted for different applications to saidbox but only by bodily removal of the cover during change from oneposition to another, one osition of said cover on said top causing t ecover and box openings to register and another position of the cover onthe top causing all openings to be closed, and means for cutting offcommunication between the openin s ine. the top end cover when the coveris placed in closed position. A

4. A can, havin a top,-an oblong rojection on said top havingsubstantial y vertical side walls, there being in the top-surface ofsaid oblong rejection an opening located on one side 0? the transversecenter line of said projection, a cover adapted to engage saidprojection at its sidewalls, there being in said cover a series ofopenings 10- cated on one side of the transverse center line of saidcover, said cover being bodily removable from, and adapted forreversible application to said projection, one position of said coverupon said projection causing said openings in the top andthe cover toregister, and the reverse position on said projection of said cover ingsto be closed.

5. A can, having a top, an oblon projection on said top havingsubst-antiafiy vertical side-walls, there being in the top-surface ofsaid oblong projection an opening located on one side of the transversecenter line of said projection, a cover adapted to engage saidprojection at its side-walls,

there being in said cover a series of openings located on one side onthe transverse center line of said cover, said cover being bodilyremovable from, and adapted for revcrsible application to said proection, one position of said cover upon said projection causing saidopenings in said top and the cover to register and the reverse of saidtop on said projection causing said openings to be closed, there beingin said cover and said top sealing-means adapted to cut oil"communication between the openings in said top and said cover when thecover is in the reverse the opening in said top.

6. A can having a top with a contour symmetrical with respect to a given'line and otherwise than'circular and a cover of the same contourwhereby said eovercan assume different positions on the can'top only bybodily removal thereof from the can during change from one position toanother, passagewaythrough the can top and causing said open-' ositionposition-and closing passageway through said cover, one position of thecover on the top causing the passageways to register to open the can tothe exterior and another position of the cover on the can causing thecan to be entirely closed to the exterior.

7. A can having a top of oblong contour symmetrical with respect to agiven line and closed over the greater part of its area, and

a cover of similar contour closed over the greater part of its area, oneposition of the cover on the can causing the can to be open to theexterior and the other position of the cover on the can causing the canto be closed to the exterior.

8. A can having outlet opening through its top and a' cover havingoutlet opening,
